THRASHING-IVIACHINI.'V

SPECIFICATION forming part of Letters Patent No. 477,507, dated June 21, 1892.

Applieationiled October 12,1891. Serial No. 408,473. (No modeld y To all whom it may concern.l

Be it'known that l, WESLEY BUTLER, of Litchfield, in the county of Montgomery and State of Illinois, have invented a certain new and 'useful Improvement in Thrashing-Ma chilies, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to certain improvements in the beaters of a thrashingqnachine and to the carriers and certain other parts; and it consists in features of novelty hereinafter fully described, and pointed out in the claims. A

The drawing represent-s a side elevation of my improved machine, the side boarding of the machine being'removed.

The frame of the machine, with its cylinder 1 and concave 2, may be of ordinary construction.

3 is an endless straw-carrier placed near the front end of the machine and running on rollers 4 and 5.

6 is an endless straw-carrier at the rear end of the machine running on rollers 7 and 8.

Between the two carriers 3 and 6 are two rotary beaters 9 and 10, which consist of wheels or disks on shafts 9a and 10, connected by slats 9b and 10b, running parallel with the shafts. Above the carrier 3 is an endless beater consisting of belts 11, provided with slats running transversely to the belts, said belts running upon rollers 12, arrangedin the form of a triangle. The body of the thrashed straw and grain as it leaves the cylinder 1 passes between the carrier 3 and the beater 11, the grain dropping between the slats of the carrier, while the straw passes on and is carried over the beaters 9 and 10 and the carrier 6. The grain drops onto the swinging pan 17 and is discharged into the cleanershoe 17a, as usual.

13 represents a comb having fingers placed a short distance apart extending across the machine and just below the endless beater 11, which fingers point in a downwardly direction and direct the straw down upon the car rier 3. The grain 'projected violently from the cylinder 1 may pass between the fingers of the comb, and some of it may pass between the slats of the endless beater 1l and enter in which case there would be two chutes 26, n

carrying the grain to the pan.

14 represents a shaker suspended by links 15 and oscillated through means of a bar 16, pivoted to a pan 17, which conveyer-pan is suspended by links 18. Motion is given to the conveyer-pan by any suitable means,

which need not be here explained, as it does not appertain to my present invention.

19 is an endless straw-carrier running on rollers 2O and 21, that receives the short straw, dac., dropping through the carrier 6, and after separating the grain therefrom, carries the straw, dac., to the straw elevator or stacker, the grain being carried backward on the inclined board 19a' and dropped into the cleanershoe 17a. The slats of the carrier 19 should be placed a smaller distance asunder than the slats of the carrier 6, as the former carries shorter material and in smaller quantity.

22 is a pulley located at the forward end of the machine and which acts as a tightener to to the belt by which the cylinder 1 is driven. This belt is shown by dotted lines 22, The lower part of the belt runs over the top of the pulley 22, so as to drive the pulley by friction.

22"is a pulley fastupon theshaftof the pulley 22, carrying a belt 22C, (shown by dotted lines,) by which the mechanism of the sweeping straw elevator or stacker is driven. By sweeping straw-stacker7 is meant the stacker having a strawcarrier turning from side to side in a horizontal plane. The device is well known, and needs no special description. Thus it will be seen that the sweeping strawelevator is not driven from the threshing mechanism,

`and consequently the obstruction of wind or accumulations of straw, while checking the motion of the straw-stacker, will not interfere with the steady running'of the thrashing mechanism. This is regarded as very important, because for perfect performance the IOO threshing mechanism must be run at a high It has been said that the slats upon the carrier 6 are placed farther apart upon their belts than those of the carrier 19.

is carried out from the carrier 6, and the slats do not in this case require to be very close,l

together; but the carrier 19, being designed to carry the short straw-blades and chaff, the 1 slats require to be closer together on this ac- It will be seen that by this arrangementl am able to produce ya double separation of the grain from the straw, as the long straw passes out on the carrier 6, and any grain that may be carried out upon this car-y rier 4falls upon the board 6 beneath the car-1, rier and is carried back into the machine, `l which is also the case with the carrier 19, that of the carrier 3, comb 13 above the carrier, .open-mouthed case 24 above the comb, the

count.

carries out the short straw, &c.

' The operation of my improved machine is, as follows: The grain enters in the usual,V manner and the straw passes `up the carrier 3, where it is Iagitated between the carrier 3j and the endless beater, and it then passes off' of the carrier onto the rotary beat-ers 9 anda 10, Where any loose ygrain in the straw isi shaken out, after which the straw passes out? on the carrier 6, while the grain, with -morelg or less 4of the chaff, short straw, and blades,'. drops on the board GPand `is carried back by",y The mai-ni part of the grain of course is dropped ontogr the pan 1.7 from the straw-carrier 3, While The matter; dropping from the board 6a is separated by 'i the lower part of the conveyer l6.

part drops on the shaker 14.

the carrier 19, while the matter dropping from ythe board 19 goes into the Icleaner-` shoe 17 a.

I claim as my invention- The obg ject of this arrangement is that the long straw proximity to the cylinder, whereby it is adapted to receive the impact of the matter projected fromthe cylinder, and an openmouthed case Within the endless beater, substantially as set forth.

2. The combination, in a thrashing-machine, of the thrashing-cylinder 1, the open endless beater 11, located in close proximity to the cylinder to receive the impact of mat.- ter projected by the cylinder, the openmouthed case 24C within the beater 11, and the spiral conveyer 25 and chutes 26, substantially as and vfor the purpose set forth.

3. The combination, in a thrashing-machine, of the thrashing-cylinder 1, the comb 13, theopen endless beater 11, which .projects over the comb, the openmouthed case 24, the spiral conveyer 25, and chutes 26, substantially as and for the purpose set forth.

4t. YIn a thrashing-machine, the combination mouth of the case being adjacent to the comb, and an open beater operating in connection with and outside of the vcase,substantially as and for the purposerset forth.

.connected with the drive mechanism of a straw-stacker, whereby the latter is operated by means of the frictional contact of pulley y22 with the drive-belt of the thrasher, substantially as and for the purpose set forth.
